operation, but with  
CC  
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. Data on the A or B bus is clocked  
into the registers on the low-to-high transition of the appropriate clock (CLKAB or CLKBA) input. Figure 1  
illustrates the four fundamental bus-management functions that can be performed with the ’LVTH16646  
devices.
